From 2629718dd26f89e064dcdec6c8e5b9713502e1f8 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 15 Mar 2017 10:08:28 +0100 Subject: fsnotify: Remove useless list deletion and comment After removing all the indirection it is clear that hlist_del_init_rcu(&mark->obj_list); in fsnotify_destroy_marks() is not needed as the mark gets removed from the list shortly afterwards in fsnotify_destroy_mark() -> fsnotify_detach_mark() -> fsnotify_detach_from_object(). Also there is no problem with mark being visible on object list while we call fsnotify_destroy_mark() as parallel destruction of marks from several places is properly handled (as mentioned in the comment in fsnotify_destroy_marks(). So just remove the list removal and also the stale comment.
